Planetary system's second Earth-size world discovered      (via sciencedaily.com) 

Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star -- the range of distances where liquid water could occur on a planet's surface. The world is 95% Earth's size and likely rocky.

Exotic wheat DNA helps breed 'climate-proof' crops      (via sciencedaily.com) 

Wheat containing exotic DNA from wild relatives benefits from up to 50 per cent higher yields in hot weather compared with elite lines lacking these genes.

Forests can help manage water amid development, climate change      (via sciencedaily.com) 

Riparian buffers helped maintain stream flow in localized areas of a developing watershed of North Carolina, a recent study found. The study projected the effect of riparian buffers amid development and climate change.

It would take 23 million years for evolution to replace Madagascar's endangered mammals      (via sciencedaily.com) 

90% of the plants and animals on Madagascar are found nowhere else on Earth, but this treasure trove of evolution is under serious threat due to habitat loss, over-hunting, and climate change. In this study, researchers examined how long it took Madagascar's unique modern mammal species to emerge and estimated how long it would take for a similarly complex set of new mammal species to evolve in their place if the endangered ones went extinct: 23 million years, far longer than scientists have found for any other island.

New battery could prevent post-hurricane electric vehicle fires      (via sciencedaily.com) 

A researcher has developed technology that could prevent electric vehicle fires, like those caused by saltwater flooding from Hurricane Ian. The technology, an aqueous battery, replaces the volatile and highly flammable organic solvents found in electric vehicle lithium-ion batteries with saltwater to create a battery that is safer, faster charging, just as powerful and won't short circuit during flooding.

Molecular mechanism behind nutrient element-induced plant disease resistance discovered      (via sciencedaily.com) 

In one of the few studies to directly investigate the mechanism underlying the effect of essential elements on plant disease resistance, scientists demonstrate that nutrient elements activate immune responses in tomato plants through different defense signaling pathways.

Elucidating enzyme gene expression in filamentous fungi for efficient biomass energy production      (via sciencedaily.com) 

A research team analyzed the regulatory mechanisms of carbohydrate-hydrolyzing enzyme production in Aspergillus aculeatus, a filamentous fungus that produces enzymes with an excellent ability to degrade plant biomass. The team found that UDP-glucose 4-epimerase (Uge5), an enzyme known for its involvement in galactose metabolism, also regulates the expression of degrading enzyme genes in A. aculeatus. This is the very first report of Uge5's roles in selective gene expression in response to different types of inducing sugars in filamentous fungi.

Subway stations near river tunnels have worst air quality      (via sciencedaily.com) 

Subway riders waiting in stations near tunnels that run below the city's rivers are exposed to higher levels of hazardous pollutants than are found in other stations. The 'river-tunnel effect,' as researchers call it, may help explain extremely poor air quality in the nation's largest underground transit system and have particular implications for stations close to rivers in general.

Chlamydiae expand our view on how intracellular bacteria evolve      (via sciencedaily.com)     Original source 

All chlamydiae today live inside the cells of hosts ranging from amoeba to animals. A team of scientists found that the ancestor of chlamydiae likely already lived inside host cells, but that chlamydiae infecting amoeba evolved later in ways unexpected for intracellular bacteria. The study is an important step for understanding the emergence and evolution of endosymbiotic bacteria, including human pathogens.

The thermodynamics of quantum computing      (via sciencedaily.com) 

In research on quantum computers, one aspect that has been mostly neglected until now is the generation of heat. Physicists now focus their attention on heat as an interference factor -- and have developed a method to experimentally measure the heat generated by a superconducting quantum system.

Shift to ultraviolet-driven chemistry in planet-forming disks marks beginning of late-stage planet formation      (via sciencedaily.com) 

The chemistry of planet formation has fascinated researchers for decades because the chemical reservoir in protoplanetary discs -- the dust and gas from which planets form -- directly impacts planet composition and potential for life.

Rodent extinctions in Hispaniola may have been caused by humans      (via sciencedaily.com) 

Hispaniola once had among the highest diversity of rodents in the Caribbean. Today, only one rodent species remains, and its prospects for survival are uncertain. New carbon dates place the blame squarely on humans.

Scientists find evidence for magnetic reconnection between Ganymede and Jupiter      (via sciencedaily.com) 

In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team has used Juno data to examine the electron and ion particles and magnetic fields as the magnetic field lines of Jupiter and Ganymede merged, snapped and reoriented, heating and accelerating the charged particles in the region.

Wide diversity of galaxies in the early universe      (via sciencedaily.com) 

New data have revealed that the structures of galaxies in the early universe were much more diverse and mature than previously known. JWST's ability to see faint high redshift galaxies in sharper detail than Hubble allowed the team of researchers to resolve more features and see a wide mix of galaxies.

Astronomers find the most distant stars in our galaxy halfway to Andromeda      (via sciencedaily.com) 

Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way's stellar halo. The most distant of these stars is more than a million light years from Earth, almost half the distance to our neighboring galaxy, Andromeda, which is about 2.5 million light years away.

Hydrogen masers reveal new secrets of a massive star      (via sciencedaily.com) 

While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star's gas disk at impossibly high speeds. What's more, they believe the jet is caused by strong magnetic forces surrounding the star. The discovery could help researchers to understand the nature and evolution of massive stars and how hydrogen masers are formed in space.

Scientists find pair of black holes dining together in nearby galaxy merger      (via sciencedaily.com) 

While studying a nearby pair of merging galaxies scientists have discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry giants are the closest together that scientists have ever observed in multiple wavelengths. What's more, the new research reveals that binary black holes and the galaxy mergers that create them may be surprisingly commonplace in the Universe.

Is 'fear' driving bias in environmental scholarship?      (via sciencedaily.com) 

Scientists understand that fear of predation affects animal behavior within landscapes. Now researchers are using a similar hypothesis -- which they are calling 'social-ecological landscapes of fear' -- to outline the detrimental effects of conservationists' failure to address negative human histories in their research.
